This is the one I use too, but with hda1, not sda1.

From memory:
- create the backing store and attach vnd, partition it (I do one ext2
partition and one swap partition). Alternatively you can use 2 partitions
from a physical disk.
- using pkgsrc/sysutils/e2fsprogs, format the ext2 partition as ext2fs (using
mke2fs), and mount it
- copy the files from a working linux system (I did this from a fedora 2
system)
- umount the ext2fs, and convert it to ext3fs using tune2fs (tune2fs -j).
- start the domain
My config file:
